Prime Meridian (Prime Meridian Labs) is an AI-powered consumer tax preparation and e-filing service that files federal and state income tax returns for free. Users upload their tax documents, answer a few clarifying questions, and the platform's AI generates a plain-language return covering W-2 employment, self-employment (Schedule C), K-1 partnership income, and multi-state situations, then e-files it with the IRS and state authorities in roughly fifteen minutes. The company is backed by General Catalyst and counts former IRS Commissioner Daniel Werfel among its strategic advisors. It is a consumer web application with no public developer API surface at this time.
